To get a sense of scale, Real Time Economics compared the 2009 output of goods and services for members of the euro zone to the output of U.S. states. The economy of Spain, for instance, is about the same size as the combined economies of Texas, Oklahoma, New Mexico and Arkansas. Italy is nearly as big as Illinois, Indiana, Michigan, Ohio, Wisconsin and Kentucky combined.
